WD40 as a lock and bolt remover

The WD40 is very effective in getting rid of a bolt or lock key that is blocked by the accumulation of dirt (dust, rust) or limescale deposits related to moisture. It penetrates the interstices and complex mechanisms of locks to dissolve all those residues that lead to friction and blockages.

In just a few minutes, combined with the back and forth movements of the key, it can unblock recalcitrant locks , whether cylinder or pump. Regular use can even prevent the seizure of exterior locks, which are very exposed to the elements.

WD40 as a lubricant for locks and hinges

WD40 is not only a great rust remover, but also a very good lubricant for the regular maintenance of your locks and door hinges. By lubricating them with the spray, you will considerably reduce the friction between the different metal parts of the closing mechanisms.

This will allow the lock to work much smoother and smoother when you turn the key to open the door. This lubricating effect also limits the wear and tear of the lock over time, thus extending its service life. This lubricant will also protect against corrosion and prevent the mechanisms from seizing thanks to its anti-greasing and anti-humidity action over time.

It can be used as the one and only product, both to unlock a rusty and seized lock and to maintain and lubricate the lock over the long term.

Application and precautions to be taken

Applying the WD40 to loosen or lubricate your doors is extremely simple. For a jammed lock, start by generously spraying the product into the gap between the door frame and the closed door. Then insert the key several times into the lock to distribute the product well inside the mechanism and leave it on for 5 to 10 minutes.

Although extremely polymorphic and practical, the WD40 needs to be used with a few precautions so as not to damage your door. First of all, absolutely avoid direct contact of the product with fragile surfaces or sophisticated finishes. In particular, WD40 can attack certain varnishes or stains. It is therefore better to spray it locally and directly on the friction points, without spraying too generously around them.

For locks as well as for hinges, always prefer localized applications in the gaps and mechanisms so as not to touch the wood of the door or its cladding. And before spraying, remember to clean the surface well to remove dust and dirt that could clump together under the effect of the product. Also, after leaving the anti-greasing agent or lubricant to act, it is essential to clean the excess well and dry the surface with a clean cloth.
